Typical cold storage facilities are illuminated by High Intensity Discharge (HID) and/or linear fluorescent fixtures. While these technologies each have their own advantages and disadvantages, LED technology now offers advantages well beyond the upfront energy savings. LED Technology Advantages in Cold Environments: Energy Savings Quality LEDs have greater efficacy than metal halide (MH) technology. This

The Northeast blackout of August 2003 affected over 55 million North Americans, including 10 million in Ontario.  I remember it quite vividly, as it was eerie to walk around the house in complete darkness and silence, and to go outside and see the night sky in all its glory.  I have fond memories of that

With the introduction of energy efficient equipment and lighting technologies in recent years, hydro users everywhere, whether they be commercial, industrial, or residential have been able to shave their utility costs. With the rate of hydro increasing and the cost of technology going there are greater and greater incentives to upgrade aging equipment and lighting

Lighting Retrofit – Case Study

Monday, 21 December 2015 by

Traditionally our arenas have been illuminated by high intensity discharge (HID) fixtures. Metal halide technology is the most common of the HIDs utilized in arenas because of the clean white light it produces along with fairly good colour rendering ability (CRI of 65-70) and efficacy (65-100 lumens/watt). While metal halide technology ensures the goal of

A battery in general is a device which makes electrically charged atoms (ions) travel from one point to another, creating electrical current. It does this by: Having one positively charged electrode (cathode), and one negatively charged electrode (anode) in which the ions travel. In the middle you must have a material for the ions to

Industry Outlook: Cap and Trade

Tuesday, 28 April 2015 by

The Ontario Government recently announced that it is joining Quebec and California in building a Cap-and-Trade (C&T) system for Greenhouse Gas (GHG) emissions. Although details have yet to be revealed, it is expected that: The next 6-8 months will be used to work out how to roll out the system. It will take about 2

The City of Toronto is following the lead of several large North American cities and looking to implement Energy Reporting and Benchmarking (ERB) on commercial and multi-residential buildings. Although details have yet to be finalized, it is expected that: It will start with commercial and multi-residential buildings over 250,000 ft², and eventually make it down

Ontario’s Electricity Production

Tuesday, 14 April 2015 by

Where does Ontario’s electricity come from? If you visit the Independent Electricity System Operator’s (IESO) website, you can find out the Ontario’s electricity grid contributors by type, on a day to day basis. Nuclear power plants supply over 50% of our electricity within the province, at all times. This is because nuclear power output does

“Engineers finding methods to make aging buildings more environmentally responsible” Efficiency Engineering was featured in a Toronto Star article on February 28, 2015. Read what our Vice President, Michael Zongor had to say about our recent work with the Oshawa site of Lakeridge Health.
